AOSP 12.0 v400.c

This is a pre-release. This is not considered daily-drivable, though your mileage may vary.
As you'll notice, there is no A-only variant at the moment. It is still undecided whether A-only variants will later appear.

When you report issues in the bug tracker, don't forget to mention which GSI version you're using.

If you want unshared_blocks/read-write system, use vndklite variants. Non-vndklite devices are capable of running vndklite variants.

Known bugs:

• On various Mali devices (Mediatek, Samsung), there are graphical glitches at many places. You can workaround this issue by setting debug.sf.latch_unsignaled property to 0 with slower performances
• Moto One Action doesn't boot
• VoLTE/IMS is broken on Mediatek devices
• Alternate audio policy breaks volume on Samsung devices
• Pixel 1/2 have no sound in-call

Changes compared to v400.a:

• Fix SU
• Enable gapps and gogapps variants
